v103 v104 27 27 * optimized even for low bandwidth connections 28 28 29 In general one can distinguish between ''' remote desktop''' and '''remote window''' solutions.\\30 While remote desktop solutions present a whole desktop environment (on JURECA we run XFCE) in a single window on the user´s workstation, remote window solutions makeapplications running on JURECA appear on the local desktop as normal windows managed by the local window manager.29 In general one can distinguish between '''full desktop mode''' and '''seamless window mode''' solutions.\\ 30 While using a full desktop mode presents a complete desktop environment (on JURECA we run XFCE) in a single window on the user´s workstation, the seamless window mode makes applications running on JURECA appear on the local desktop as normal windows managed by the local window manager. 31 31 32 The full-blown and one-click solution for remote visualization providing a remote desktop on frontend nodes and compute nodes is provided using '''Virtual Network Computing (VNC)''' over the login tool '''Strudel'''.33 We recomment to use VNC + Strudel as our first choice as it is integrated into our batch system at the moment most efficiently.34 For access to remote windows we recomment '''X Persistent Remote Applications (Xpra)''' as a light-weight solution.32 The full-blown and one-click solution for remote visualization allows a remote full desktop on frontend nodes and/or compute nodes is provided using '''Virtual Network Computing (VNC)''' over the login tool '''Strudel'''.\\ 33 We recomment to use VNC+Strudel as our first choice as it is integrated most efficiently into our batch system at the moment.\\ 34 For access to remote seamless windows we recomment '''X Persistent Remote Applications (Xpra)''' as a light-weight solution. 35 35 36 36 \\ … … 48 48 49 49 '''VNC + Strudel''' (Scientific Remote Desktop Launcher) 50 * provides a complete graphical and '''remote desktop'''50 * provides a complete graphical and '''remote full desktop''' 51 51 * survives disconnect & reconnect 52 52 * supports easy start of remote visualization jobs over the batch system (including reconnect). … … 79 79 80 80 '''Xpra''' (X Persistent Remote Applications) 81 * provides a '''remote window''' solution.82 * this is a'''replacment for ssh -X'''81 * provides a '''remote seamless window''' solution. 82 * this is the best '''replacment for ssh -X''' 83 83 * survives disconnect & reconnect 84 84 * every window appears as a separate window on the user’s desktop 85 85 * graphical window is encoded to a video stream and send to the user´s desktop 86 * focus is on fixed frame rate butdynamic frame quality86 * focus is on fixed frame rate and dynamic frame quality 87 87 [wiki:vnc3d/xpra ... more details] 88 88 … … 137 137 == Comparison of possible Remote Visualization Solutions == 138 138 139 ||= Features =||= '''VNC''' =||= '''Xpra''' =||= '''ssh -X''' =|| = '''NX''' =||= '''RDesktop''' =||140 || Stability || || || || ||||141 || server-side rendering || VirtualGL || VirtualGL || --- || ||||142 || disconnect & reconnect || || || || ||||143 || Performance over slow link || || || || ||||144 || disconnect & reconnect || || || || ||||145 || Seamless mode || || || || ||||146 || Full Desktop mode || || || || ||||147 || Session Shadowing || || || || ||||148 || no local X-server || || |||| || ||149 || Main Issues || || |||| || ||139 ||= Features =||= '''VNC''' =||= '''Xpra''' =||= '''ssh -X''' =|| ||= '''NX''' =||= '''RDesktop''' =|| 140 || Stability || ++ || ++ || - || || + || ++ || 141 || Performance over slow link || + || ++ || -- || || ++ || + || 142 || server-side rendering || VirtualGL || VirtualGL || - || || VirtualGL || - || 143 || suspend & resume session || YES || YES || - || || YES || YES || 144 || Seamless mode || - || YES || YES || || YES || YES || 145 || Full Desktop mode || YES || (YES) || (YES) || || YES || YES || 146 || Session Sharing || YES || YES || - || || YES || - || 147 || no local X-server needed || YES || YES || - || || - || YES || 148 || || || || || || || || 149 || Main Issues || || || || || || || 150 150 taken from https://winswitch.org/documentation/protocols/choose.html 151 151
